net: sfp: return the number of written bytes for smbus single byte access

Browse source

[ Upstream commit 13ff3e7242 ]

We expect the SFP write accessors to return the number of written bytes.
We fail to do so for single-byte smbus accesses, which may cause errors
when setting a module's high-power state and for some cotsworks modules.

Let's return the amount of written bytes, as expected.
